Artificial intelligence is being taught by thousands of office workers around the world. Before an A.I. system can learn, someone has to label the data supplied to it. Humans, for example, must pinpoint the polyps. The work is vital to the creation of artificial intelligence like self-driving cars, surveillance systems and automated health care. It is not exactly futuristic work. A.I. researchers hope they can build systems that can learn from smaller amounts of data. But for the foreseeable future, human labor is essential.
